摘　　要：提出将闪蒸淡化技术应用于质子交换膜燃料电池(PEMFC)分布式发电系统。该系统可在PEMFC发电的同时利用余热进行淡水生产,实现系统能量的梯级利用。通过热力学计算得出该系统在典型工况条件下的能流分布,分析影响系统发电和淡化性能的关键运行参数,评估系统的综合能量效率和经济性。A conceptual design was presented, which integrates flash desalination process into proton exchange membrane fuel cell （PEMFC） distributed power generation by recovering the heat from the PEMFC for potable water production. In this way, it can become an example of a PEMFC gradational energy utilization system. Thermo- dynamical analysis was also performed to estimate the energy distribution of the system at typical operating parameters and the effect of operating parameters on the performance of electricity generation and desalination was discussed. At last, the overall efficiency and economy of the system was also evaluated.
